Hey guys, was using my SII a few hours ago, and I put it down at ~48% battery life. I had it charging off the USB of my PC. I don't have Samsung Kies installed, or anything. I was purely just charging it, on stock rom/bootloaders/no-root.
I went to pick up my phone a few minutes after, and all the sudden the phone won't turn on anymore.
I've tried pulling the battery, I've tried letting it run through any power still in the circuits, by having the battery out for 30+ minutes. I tried the "pull out battery, hold power for 10 seconds, then pop battery back in," to no avail. I've tried download mode, I've tried using my old Captivate jig.. It doesn't seem to be responding if I plug it in(no heat.)
Any ideas? Going to bring it back to the AT&T store tomorrow to try and get a new one.. I really hope they don't give me any ****. -_-;
Update:
I went to the AT&T store today since they just got a new batch in. Unfortunately, my faulty phone actually wasn't a problem with the phone.. It was a problem with the battery.
Somehow, the battery shorted out the entire phone, and killed it. The reason why I suspect this, is that I asked for the old battery in the new phone they were giving me. Sure enough. That phone is now a brick, also..
Thankfully, they were nice enough to give me a different one and not shove the newly dead one down my throat..
So.. Not quite sure how that happens, but sure enough.. That battery is a Galaxy killer.

You got a dud piece of hardware. Shouldn't have any problem exchanging it.

The only thing you didn't mention is using the stock charger to charge the battery for an hour or so. Did you try that? It could be a dead battery. And once the battery is critically low, your PC can't supply enough juice to charge the battery.

Yes, the USB charging mode on the computer sucks. Its easy to draw a deficit of power running off the computer. I had 8 percent and plugged in via USB and within a minute. Or two it was almost dead, fell to 1% in literally 5 mins. It was almost like it was pulling power FROM. The phone
The stock wall charger is 700ma IIRC. Most PCs can output only 500ma max (USB 1.0/2.0 standard). The 700ma is needed when battery level is really low. So, don't leave home without the wall charger.
I tried plugging the phone into the wall charger, to no avail.
Won't even show the charging screen, or get warm.
Bah! Hopefully the AT&T store will have new ones in stock tomorrow.
Bump.

That's surprising - did they confirm that the phones remained dead even with a "good" battery in?
The charger chip in our phones (MAX8922) has plenty of short-circuit protection mechanisms. (Battery prequalification mode limits current to 90 mA at extremely low batt voltage, and it also has temperature limiting.) So a shorted battery shouldn't have been able to damage the phone.

Indeed, we tried swapping the "new" battery into it. Both of the phones were gone. I never even thought it was probable. Maybe it was just a bad batch? Who knows.
Either way! New phone smell, is great. =P
Hey guys! I'm needing some advice/tips.
I've had my g tablet for about a year and lately it really has started acting up. The power reading on the tablet was either like 100% or dying. Last week it just crashed when loading even though I had charged it. I figured the battery was bad and bought a replacement on Ebay, The power socket had been loose for awhile and the whole thing actually fell out of the tablet when I took it apart. I had the socket soldered by a local guy at radio shack since I have no experience soldering. I replaced the battery with no problem and now the tablet will not charge. I can not tell if the new battery I bought is defective or just need a full charge since it seems my tablet won't charge with either battery installed. The connections from the power socket to the motherboard look good, but I'm wondering if the repair man could have messed up the soldering. When I put the original battery in, the tablet will boot up for a bit and then die, but I get nothing from the new battery. I left the new battery in and plugged in the charger thinking maybe the indicator light had gone bad, but that didn't make a difference. I just wondered if anyone had some suggestions for me. (I've been taking apart and repairing my own electronics for years now, so I am confident no damage occurred while I have been tinkering). Any ideas are much appreciated! Thanks!
See this thread. If you can boot into the ROM or ClockworkMod, then you can use the awk script I've written to find out what your battery is doing--charging, discharging, full, RSOC, etc.
Hello all!
I recently purchased a used Droid Razr Maxx from a co-worker. The lcd screen was cracked so I replaced it. I took apart the phone completely and reassembled it with the new screen in place. The phone turns on just fine, the Motorola icon shows up and it gets to the charging battery icon with 5%, but after a few hours of letting it charge, it stays at 5% and wont turn on. Keep in mind, the phone has been charging for two hours from the time this post was made.
My question is, did I somehow damage the battery when operating internally? I can replace the battery if needed.
Another question. If I damaged the motherboard, would the phone turn on at all?
I am kind of wondering if there is a certain thing I needed to do before plugging it in.
To answer any questions that might be asked: The battery was completely dead when I did repair the screen. The charger is a wall usb charger, not plugged into my computer. I did place all the components inside the phone, to the best of my knowledge. I have had experiences when it comes to internal repair.
check for how long this 5% charge remain. it usually happen due to problematic battery guage

Morning now. The battery is still at 5%. The phone shuts off soon as the charger is not connected. Does not seem to hold a charge. Think I should buy a new one?

It could be a faulty charger.
Normally, If the battery is poor, it won't hold charge but it won't stick to a particular percentage. It will only discharge sooner. But given the fact you got the phone dead, it might as well be the battery.
Worst scenario, you damaged the charging port.
I'd begin with using a different charger, if that doesn't work, try another battery.

I have used other chargers and they all work for my other phones, just not this one. I am hoping it's a dead battery and not something to do with the motherboard. My friend wont let me dismantle his phone to see if it's the batter, lol.
Just the clarify, the phone doesn't boot up completely, only to the charging screen. The battery icon with 5% shown. When I unplug the phone from the charging screen, it just dies. Will not even boot up to the phone animation.
I purchased a battery replacement off of Ebay. It'll arrive in a few days. Let's hope this works!
Still could be the charger. Did you check voltage and amp specs? 850amps 5.1v
This phone can be picky. First razr I got had broken screen, repaired it and found myself in the same situation.
Connecting to a laptop would not charge it. Only stock charger. IPhone charger or chargers designed for iphones will not work.
Edit: When replacing battery, position is critical. If battery terminals are a little bit displaced it will not turn on.
Displacement can be minimal or imperceptible but will cause troubles. If possible don't place cover before checking that it turns on. (please avoid touching circuits or battery terminals or will get worse).

That was exactly the problem....
I got the new battery, but not 24 hours later, I was realigning the cables inside it (like the front facing and rear cameras, along with the WiFi antenna) I slightly moved the replaced battery and the cable to the battery to the motherboard tore itself. After a long face-palm moment, I got the old battery back in place and realigned it very carefully. It turns out it still works, but I am out a new battery.
Apart from the battery, I need to find out why the front speaker won't work. Either the speaker is damaged or something needs to be in place correctly, besides the cable. Also need to get some adhesive gel to bond the screen and case together.
Damn I really had forgotten about that speaker. The fact is it tends to break. It has very fine copper wire winding that can break when you remove it the wrong way.
Having no experience I pulled not knowing that speaker is glued to motherboard. At that time I didn't knew it and thought that little bar left was part of the motherboard.
Since you disassembled almost everything, that must be the reason it is failing. If it is not that, it is badly plugged but I really doubt it.
Alas Never fixed it, so i can't tell correct process to reassemble or disassemble that speaker. Instead I searched for apps that would activate loud speaker automatically during calls.
Would have been nice to fix it but I got the opportunity to acquire a RAZR maxx so never touched and sold instead.
Removing that glue might involve using a hot air gun. So that you don't damage motherboard removing by force. (But again too much heat could Fry motherboard)
Maybe someone could share it's experience?
About that screen, Remember to have read about a 3m adhesive spray in some thread.
Also some one just passed hot air that melted original glue but it would be better not to play with heat over a battery.

So what happened was, my original battery died, it expanded and didn't last long anymore.
That's when I replaced it with new battery (from ebay, not sure if I can link it here?).
The issue is, basically my phone wont boot with the new battery.
When I hold the power button, it starts to boot like normally, I see the oneplus logo but then it just instantly shuts down.
Even if the battery is fully charged and the phone is plugged in with charger.
I managed to get my phone working like this:
I plugged in the charger and booted the phone with the original battery, then I disconnected the original battery and managed to keep the phone on, powered by only the charger, then I plugged in the new battery.
That's how it stays on and even shows the correct battery percentage. I've been using my phone like this for few weeks now, but the problem is that I can not shut down my phone. It wont boot with this new battery.
So every time I have to update rom or something like that, I have to put the original battery back. That is a problem.
I have no idea why it wont boot with new battery, cause it otherwise works just fine.
The battery from ebay is colored red and I also have second battery that's called "x-longer". Both of them does this exactly same thing.
If anyone knows what's going on, I'd appreciate if you could take some time and help me. Also sorry for my language, I hope you understand.
Thanks,
Ruuppe
Don't ever trust the battery's from eBay. So many times I've bought 'OEM" or "Original" and been fakes. Just because the wrapper on the battery is the same doesn't mean the battery inside is. Same goes for micro SD's also and pretty much everything else. Spend the extra money and get it through manufacturer. Or a reputable company someone can confirm legit. Send the battery back and ask for full refund.

That's what I did. I got full refund from the ebay battery. And the other one (branded x-longer) is from legit company. The battery works fine and keeps the phone on, the only problem is that the phone wont boot with it. What causes this problem?
Edit: Also, the original battery isn't red like the one from ebay, it's black with some silver.

Call customer support maybe can only use original batteries.

Hi, sorry for delay on answering. I contacted the customer support, and they said they wont sell original batteries nor you can't get them from anywhere.
They also didn't know why my phone wouldn't boot on these replacement batteries.
So, if anyone has any idea, I would be more than happy to know what it could be.
Thanks,

Hi everyone, I got a poco f1 from a friend. He used it quite normally. The cellphone was off for about a month - it didn't work. After a month I tried to start it however unsuccessfully, poco f1 is dead, I tried to charge it but it can't. What could be a malfunction? Help if you know and thank you very much
First, try using a different charging cable and brick. If it doesn't charge, Check if it can be read using a computer or laptop. If it still doesn't work, then the issue may be the charging port. If that's the case, if you are still covered by warranty, then go to xiaomi store. If not covered, go to a proper technician.
Btw if the device can be read on a computer, then it may just be a boot issue. Just flash again.
Does the white charging led light up when it's on charge?
If not, have you tried leaving it on charge for an extended period?
I've had difficulties with phones in the past after batteries have fullly discharged - eg the Moto G5 had some battery protection "feature" that stopped it starting up if it thought the battery was fully discharged - it was a bit over sensitive so would sometimes assume the phone was fully discharged when it wasn't
Try leaving it on charge for 24 hours or so then holding down the power button for for at least 20 seconds with it still on charge
If you have no luck and the warranty is out, get to a repair shop (or disconnect and reconnect the battery if you're confident to open it up - for a while I was getting sporadic shutdowns with my F1, following which it wouldn't take any charge, the battery light staying off when plugged in. This was all fixed by tightening the screws securing the black motherboard plate, the cover which retains all the connectors - not sure why but it seemed something, I suspect the antenna connection, had come loose. Since doing this about 5 months ago I've had no further shutdowns and my phone is usable again, having been completely unreliable before)
One trick that worked on some old Nokia phones was to charge it plugged to a computer instead of plugged to a charger - but as said elsewhere, if the battery is completely dead, YMMV.
Also, try to press and hold the power button and while doing that, plug the phone to the charger and then release the power button.

I guess your battery is dead
I have same issue, however I think my one is a motherboard charging IC issue. Does anyone know a way I can get it cheap from India, as I’m in the UK. India have it for around 9999 rupees which is about £10(+international shipping). I’ve ordered a charging port replacement from AliExpress to see if that solves the problem. However I don’t think that will work. No idea how my motherboard got damaged in the first place. I replaced a cracked screen myself and the phone was working fine for a few weeks, then it stopped charging all of a sudden. My PC also detects it/can access files doesn’t charge it. A new battery powered powered on the phone but again didn’t charge. Tried different adapters and cables too. Any experts out there know whether this is a motherboard issue or just a charging port issue?
If the phone is OFF for a month, then it is probable that the battery has gone down to a point that the BMS has shut it down. The BMS won't allow you to charge the battery because, in its own assessment, the battery is dead. Best way to test this case is to have another Pocophone with a good battery (or just a new battery altogether), detach the cable from that and test on yours. This may or may not work but this is one of the easiest to test and a new battery is easy to acquire.

Before you do that, just try leaving it in charge for 24hrs as suggested above, though it does look rather as if the OP has nicked off so won't be using any of these sage words!
